ASX340CS: 1/4-Inch Color CMOS NTSC/PAL Digital Image Sensor
Pin Descriptions and Assignments
Pin Assignments
Pin 1 is not populated with a ball. That allows the device to be identified by an additional
marking.

Notes
Input
Input
Input
Input. Must always be driven to high via
a pull-up resistor in the range of 1.5 to 4.7 k.
Input/Output. Must always be driven to high
via
a pull-up resistor in the range of 1.5 to 4.7 k.
Input. Must be permanently tied to VDD_IO or
GND.
Output. Output enable is R0x0032[13].
Input. Internal pull-up is permanently
enabled.
Output enable is R0x0032[13].
Output enable is R0x0032[13].
Input/Output. This interface is disabled by
default. Input buffers (used for GPIO function)
powered down by default, so these pins can
be left unconnected (floating). After reset,
these pins are powered up, sampled, then
powered down again as part of the auto-
configuration mechanism. See Note 2.
